60+ Trace Minerals from the Ocean
Seaweed concentrates every trace element from ocean water — iron, manganese, zinc, boron, molybdenum, copper, and dozens more. A single amendment that covers the entire micronutrient spectrum.
Natural Growth Hormones
Contains cytokinins and auxins — natural plant hormones that promote cell division, root initiation, and stress recovery. These compounds are why kelp-treated plants consistently outperform.
Stress Resistance Booster
Kelp-treated plants show improved tolerance to drought, frost, heat, disease, and transplant shock. The natural hormone and mineral package primes plant defense systems.
Root Growth Promoter
Auxins in kelp meal directly stimulate root initiation and branching. Add to seed starting mixes, transplant holes, and new plantings for measurably better root establishment.
Feeds Soil Biology
Complex carbohydrates and alginic acid in kelp meal feed beneficial soil microbes, improving nutrient cycling, soil structure, and disease suppression in the root zone.
250–500 sq ft Per Bag
At 1–2 lbs per 100 sq ft, one 5 lb bag covers 250–500 sq ft. Low application rates make kelp meal economical despite its premium-ingredient status.
Universal Amendment
There is no plant that doesn't benefit from kelp meal. Vegetables, flowers, trees, shrubs, lawns, houseplants, seed starting — add it everywhere, every season.
Trusted by 20,000+ Growers
Developed in Littleton, New Hampshire. Sold nationwide on Amazon, Walmart, eBay, and theoldcobblersfarm.com.
